CINDER-NOTCH STOPPER.

Application filed December The present invention relates broadly to animproved form of apparatus by means of which. the cinder notch or cindertap hole of a blast furnace is adapted to be closed or opened at will,and more particularly to an improved form of mounting and operatingmechanism forsuch anapparatus. I

It has heretofore been proposed in the art to which the presentinvention relates to prom videa furnace,bot-tiruqv apparatus or cindernotch stopper of-the typesuspendedfrom a suitable overhead supportby aplurality of levers, one of thelevers being of special construction andcooperating with. pins and 1:- slots in such manner as to slightly raisethe rear end of the botting-arn'iduring backward movement thereof inorder to cause the front of the betting arm to travel in a substantiallystraight line. Such constructions,

2 while effective generally for the purposes contemplated, have beenobjectionable due to mechanical diflieulties involved in the construction and operation thereof. .4

It has also been customary in installations of this character toutilize-actuating means remotely positioned relative to the :bottingapparatus itself. This has necessitated special operating connectionsand special constructional features for each installa'tion.

The present invention has for certain of its objects to provideanimproved apparatus of this general charactensuch that a rigid andeffective support for the botting armis provided, the support being ofsuch cons StlllCtlOll' that the botting end of "the arm is moved in asubstantially horizontal plane without sliding friction of the characterhereto fore necessi fated Another object of the invention is to providean apparatus which is in effect self-contained, the: actuating meansconstituting a component part thereof, and itself suspended or carriedby the support for the botting arm. i

In the accompanying drawings there are shown, for purposes ofillustration only, certain preferred embodiments of the presentinvention, it being understood that the'drawings do not. define thelimits of my invention, as changes in the construction and operationdisclosed therein maybe made without depariing either from the spirit-ofthe invention or the scope of my broader claims.

The present apparatus, in accordance with this invention, is adapted foruse with furnaces of usual construction embodying a cinder notch or acinder tapping hole 2 which may be provided with the usual monkey cooler3 and cinder monkey cooler 4:.

Above thetapping hole 2 the furnace may be provided with a suitablyconstructed supporting band or girder 5 to which is attached a U-shapedyoke 6, as illustrated in detail in Figure 4. Cooperatingat one end witha yoke (3 is a horizontally extending beam structure 7 constituting anoverhead support for the cinder notch stopper. The opposite end of thebeam structure 7 extends below the usual bustle pipe 8 and is securedthereto by straps 9 passing therearound. In order to permit the support7 to be correctly adjusted horizontally and vertically to bring theparts of the apparatus into accurate alignment with the cinder notch,the sides of the yoke 6 are provided with elongated openings 10 toreceive bolts 11 passing therethrough, while the bottom of the yoke isprovided with a similar opening 12 for the reception of a bolt 13. Thebolt 13 is of such length that it-is adapted to cooperate with shims 14,any desired number'of which may be added or removed at will. Thisconstruction enables the yoke (i to be firmly secured to the blastfurnace, and at the same time enables substantially universal adjustmentof the support? 9 1 The apparatus may conveniently be constructed tocompr'me a betting arm having one end shaped to provide anlemergencysledging head 16 by means of which the, bar may be moved by means of asledge or the like should it become stuck to an extent to require suchmeasures. Projecting forward- 1y f-romthe botting' arm is a botting' bar17 on'the front"end'of which' is a stopper or bott 18"cooperating withthe cinder monkey cooler. Y

The-bottingarm is conveniently carried by a system of links,"-suc'hsystem ooinprising a front link structure 19 and a rear=compound linkstructure 20. The "front link structure comprises spaced side armscooperatin at their lower ends with a pivot pin 21 and at their upper;ends with a" pivot pin 22 extending through the support 7 Intermediatetheir-ends the"'side'arms carrya cross head 23 having a slot 24 throughwhich -'passes-a-transverse1y extending pin 25. "The compound link strncture for the rearof the bottingarm comprises side arms having apivotal conne'c'tion 26'--'at their'lower ends with the 'botting arm,and having upper pivotal connections 27 carried by the lower ends ofauxiliar -links 28 and constituting, in efiect, crank" arms mounted at-their 'upper ends on a common shaft29-e'xtcnding transversely ofthe'support 7 *By reason of-this construction; it 'willbeapparentthat byactuating the crankarms 28 thepiwotpoints 27 about whichthe link.structure moves mayg-be. varied at-wilhdhereby causing the rear endofthe bottingarm to travel through any desired path. Inasmuchns it isdesirable to have the front end of the betting arm travel in asubstantially horizontal direction until it is clear of the furnace, itis nec essary, during the rearward movement of the apparatus, togradually swing the crank arms 28 in a counter-clockwise direction, asviewed in Figure 1, thereby effecting a gradual raising of the rear endof the betting armand a consequent lowering of the front end thereof tocompensate for the tendency ofthe link structure 19 to raise the bettingarm.

For effecting the foregoing operation, there may be'provided actuatingmeans comprising a cylinder 30 havin trunnions 31 ournaIed in bearings32 carried by the suport 7 and projecting downwardly thererom. On theouter end of '{one of the trunnions 31 there is secured a gear segment33,

"the teeth of which mesh witha pinion 34 on one=end of the'shaft 29.-Byreason of this construction. it will be apparent that tiltingmovement of the cylinder will be effective for-imparting-rotation to thepinion 34 and consequently to the shaft 29 and crank arms tween thepiston rod and the cross head 21;

whereby rearward movement of the piston initially imparts no movement tothe botting arm. At the end of the travel of the pin 25 in the eye 36,however, a sudden blow is imparted to the apparatus which is ctfectivefor releasing the same under all normal operating-conditions, andthereupon continued-travel of the piston rod 35 will be effective formoving the botting arm from the full line posit-ion illustrated inFigure 1 to the; dotted line position. During this movementthe cylinderwill be caused to swing-inaclockwise direction about its [run- .nions 31due to the. path of travel of the pin 25. This movement will in turn beeffective for movingthe gear segment 33 in a clock wise directionforrotating the crank arms 28 in'a counter-clockwise direction for therebygradually lifting the pivotal supporting points 27 and consequently therear end of the betting arm.

As a safety measure, there may be pro vided a safety latch 37 having apivotal mounting 38 on the front cylinder head 39, the safetylatch-comprising depending jaws 40 adapted to ride over a pin 41projecting from opposite-sides of the piston rod and thereby lock thesame in the dotted line position of Figure 1. For releasing theapparatus, the. latch is provided with an upwardly extending release arm42 to which may be connected a cable 42 and running to the cast housewall whereby the apparatus may he released from a distance. It will beunderstood that the cylinder may be provided with fluid connections 43at the opposite (nds thereof whereby fluid may be directed to orexhausted from the cylinder as required to effect operation of thepiston rod 35.

It will be apparent to those skilled in the art that a compound linkstructure might be utilized for both ends of the betting arm to therebyobtain 'a modified path of travel of the bott, it only being necessaryto so bodily move the effective supporting axis or axes as to compensatefor the normal tendency of the bott-ing arm .to. rise due to the arcuatepaths through which its supporting .link structures move. In theinterest, however, of simplicity of construction and operation, a singlecompound link structure is in most cases preferable.

In Figures Sand 6 of the drawings there is illustrated a slightlymodified embodiment of the invention, showing another form of compoundlink support. In these figures parts corresponding to parts alreadydescribed are designated by the same reference characters having a primeafiixed thereto.

in some blast furnaces the cooler 50,-indi- (rated in dotted lines'inFigure'l, is projected outwardly a considerable distance'fbeyondthefurnace, as indicated, for example, in Figure 5'. {In such c'asesitmay be desirable to extend the length of movement of the bott in asubstantially horizontal plane and then suddenly break the lineof-travel of the bott after it clears the cooler, to. thereby permit itto move upwardly to a position *in whichit is out=f the way.IIIfSUClI-CaSES the link structure 20 comprising-the crank arms' 28may-be of slightly modified con-" Asillustrated in- Figure"5,thecrankarms 28' are not operatively connected struction;

with the cylinder30. At least -one of these arms, however, iseXtended-rearwardly in substantial parallelism-to the support '7 andcarries at its outer end a='counterweight-;51-,= the counterweighttendingnormally to urge the partsinto the full line position'indicatedin Figure {Upon movement of the botting arm backwardly under theinfluence of its actuatlng mechanism thej'llnk structure 19 operates inexactly the manner-before de scribed. The link-structure 20, however,starts moving about the pivots 275,: s0 that the rear end of the bottingarm is caused to rise relatively faster thanth'eirfront end and therebycompensate for the are through which the link '19 moves: During thisn'lovement the effectiveness :of the counter weight is partlyovercome'to the extent that the pivots -27 move from their-full lineposition to theirdaslrand-dotposition of Fig ure 5. At-this'time the Ushaped projec tion 52 constituting an integral part of the crank arms 28occupies the position illustrated in chain lines in Figure 5 inengagement. with the/link structure 19.

through the projection 52 for quickly mov ng the pivotal points'27fromtheir chain line position to their dotted line position, thcrtaiponcausing movement of the botting arm, botting bar and bott from the chainline position to the dotted line position." :It will be apparent fromthedrawings, how'- ever, that. this rapid movement of :t e pivot points 27'does not occur until after thebott: has cleared the cooler. The'movementis obviously effective for relatively lengthening the link structure forthe rear-of the botting arm. which in turn'tends to quickly-raise thebott and upon continued movement carry the apparatus to an upperposition-iuwhich it is entirely out'o'fthe way-. g r

During the return movement of the parts the. counterweight tends toswing the crank arms 28' from the dotted line position to the chain lineposition as rapidly as permitted Continued movement of the bottingarm iseffective shaped projection 52 is omitted, and its functionaccomplished-by a==trip rodopera-= tIVCly connected at one end to thepivots-127,

and at the opposite end slidably mounted in i a i pin61-1rotatablyxcarried 'in' bearings 62 in the-:crosshead 123. At'anintermediatepoint the trip rod-is provided :with a stop or shoulder-63,and-intermediate this stop is acompression or buffer spring 64:

, l/Vith this construction =the operation is similar to that beforedescribed, rotation of the rear link structure 120 continuing about thepivots 127 until the movement of: the parts brings the end. ofthecompression spring 64 into contact with the stop 63.'limreafter.continued movementwill break thcjoint between thelinkstructure'120 and the'crank arms 128, as before set forth. Thebuffer springrelieves the parts-of the jar to which they'aresubjected bya construction as showirinl igure In all-embodiments of the-inventionthe structure issuchthat the crank arms change the effective position ofthe axis or pivots carried thereby, the crank thereupon compensa-tngthenormal-tendency of at least the front end of the botting arm to move up\\'ardly.' This construction, embodying a shaft pivot in at" least oneof the link supports, has been found to be highly desirable.

Certain advantages of the present invention arise from the provisionof-a compound link support for at least one end of a bottng arm, thesupport being of such construe tion that the effective pivotal-axis ofthe supporting links is varied during the operation of the apparatus tothereby cause the bott to travel in the desired direction.

Further advantages arise from the provision of actuating means in theform of-' a cylinder of such construction that it is bothcffec'tive forimparting a'jar to the bott for loosening the same from the monkey andfor effecting a change in the position of the axis of at least one ofthe supporting means.

Still further advantages arise from the manner of carrying the overheadsupport whereby it may be substantially universally I adjusted to bringthe bott into the exact po sition required, thereby facilitating installation of the apparatus and enabling iacu- &

rate adjustment as required by continued use.

Additional advantages are inherent in the utilization of actuating meansconstituting a component part of the apparatus and suspended from thebustle pipe or otherwise carried by the overhead support in proximity tothe parts which it operates.
